ELECTRIC GIIUSTER- LAMPBOD Y'AND'SHADEHOLDER.

Application filed June 3,

the hollow body which is normally "formed of two semispherical portions together, and

which will also rigidly mount the shade thereon. l v

Another purpose of the invention. is. to

providemeans/whereby the same securing strueture'canbe'utilized with standard littings of different sizes without in any way interferingwith the body mounting and with but slight change in the elements used. In the standard structures now used for secur ing'lanip -shades on clusters oi this character, two sizesiare principally applied and heretofore it has been necessary where a cluster is equipped with the securing means of one size to remove the securing means and utilize a different one in order to use the standardparts of the other size. With our invention, a standard smaller size may readily be changed to accommodate the larger size by the simple addition of two elements which fit in wit-h the other standard securing means used with the sma-ller size.

Other objects and advantages of the in vention will appear as the description proceeds when takenin connection with the accompanying drawings. However, we wish it to be understood that we do not intend to limit ourselves to the exact details shown and described, but that we intend to avail ourselves of all such modifications as would occur to one skilled in this art and as would fall within the scope of the claims.

In the drawings:

Fig. 1 is a side View partly in section illustrating the invention;

Fig. 2 is a sectional view showing the mounting means as utilizing the standard Fig. 3 is a front view of the supporting member upon which the shade rests.

Referring now in detail to the drawings, the numeral 5 indicates the stem or standard which supports the hollow body 6 constructed in this case of the lower portion 7 and the upper portion 8 and having a pair of lamp 192?. Serial No. 193,262.

As shown, the upper portion at the hollow body is provided at its junction with the.

lower portion with the outwardly and downwardlvextending lia-nge 11 which its :over 7 In order to clamp the hollow body downupon' the member-18, weprovide the member 16 which has scrmv-thiezicls engaging the stem 15 whereby itmay be screwed down to in the portion 13 or then'iemberqlil clamp the portion 14 ot the hollow body 8 d between it and the portion 13 ofthe member 12. This member 16 as shown more clearly n Fig. 2 has an external shoulder at 17 for receiving the finishing tubular member 18 thereonf The member 16 is also providedwith an enlarged opening at 19 extending downwardly throughoutthe greater portion of its length and screw-threaded for a purpose which will presently appear. Now in using the standard small size fixtures and finishing top member for securing the lamp shade, we provide the flat disk 20 which is screw-threaded to receive the member 15 so that it may be threaded down to rest on the tube 18. In order to make a firm.

support for thismember, we also depress'it-as at 21 so as to fit inside the tube '18 and prevent lateral movement between the stem 15 and the tube 18. The member 20 being provided with the fiat portion on top forms a good support for the lamp shade which is secured in place by means of the finishing nut 22 screw-threaded to receive the top of the member 15.-

' Now if it is desired to change to the large standard size, the finishing cap member 20 is removed together with the cap 22, and the tubular member 23 is screw-threaded into the hollow portion 19 of the member 16, the member 23 being tubular so that it will read ily receive the member and being screw threaded throughout its length serves also to receive the supporting member 24 which is provided with a screw-threaded opening to fit the member 23. The shapeof the mem ber 24- is substantially the same as that of the member and it is also provided witha shoulder as at 25 for preventing any lateral movement between the member 23 and the sleeve 18. The lamp shade 26 may then be placed upon the member 24 and secured thereon by means of the large finishing nut 27 to complete the structure of the lamp. Thus, it will be seen that by the insertion of the member 28 the large finishing members such as 24 and 27 which are the larger standard size may be applied. directly to the securing means of the hollow body fitted with the stem 15 to receive the smaller standardsize fittings and in this Way considerable re-' this art,and having thus described our in vention, What We clalm and desire to secure by Letters Patent of the United States is:

1. Lamp shade mounting means for electric light clusters comprising a screw-threadour names this ed stein projecting from. the cluster body, a

clamping member screw-threaded thereon and having an enlarged recess extending downwardly from the top thereof a sleeve on said 'member projecting thereabove, a tubular member detachably mounted in said recess and surrounding said stem,"a diskmember resting on said sleeve and screw-threaded,

on said tubular member, and. a securing tubular member detachably mounted in said 'recess and surrounding said stem, a (118k member resting on said sleeve and screw threaded on said tubular member, and a securing member screw-threaded on said tubulamp shade thereon, said'diskha'ving means thereon preventing lateral movement between said sleeve and said tubular member. In witness whereof, We hereunto'subscribe vIo roR R. DESPARD; HANS Q'RIPOPP;
